A preliminary test of solar roof top in Medan city of Indonesia

Abstract

A friendly city must be developed with low carbon emission to make it also friendly for climate change. Solar energy resource is abundantly present around the roof. Solar roof top is a promising application to build a friendly city. In this work, a preliminary test of solar roof top in Medan city of Indonesia is carried out. Eight Solar PV modules are installed on the roof of a building in Medan. The specifications of each module are as follows. The rated power and Voltage are 250Watt peak and 30.5 Volt, respectively. The dimension and the weight of each module are 160 mm × 992 mm × 35 mm and 19 kg, respectively. The solar irradiation, voltage and current are measured and recorded. The performances of the system are discussed.
